Quiescent T cells possess a condensed chromatin, whereas proliferating T cells have a more open chromatin configuration.
It can be concluded that CBHA can improve the transcription activity of these genes, which should be related to the more "open" chromatin configuration.
These HDAC inhibitors (HDACi) work to prevent histone deacetylation, facilitating a more open chromatin configuration and leading to increased gene transcription.
As a result, it is believed that histone acetylation primarily results in a more "open" chromatin configuration, serving as a "mark" of active gene transcription.
Further, RNA likely contributes to architecture and regulation, with repeat-rich 'junk' RNA in euchromatin (ecRNA) promoting a more open chromatin state.
The longer E1 E2 distances for XL indicate more open chromatin structure of the dystrophin gene on this chromosome in contrary to closed structure on XS.
Embryonic gene activation (EGA) in pigs happened at the 4-cell stage (Maalouf et al., 2009), and the increase of global histone acetylation was mainly discovered at the 1-cell and 2-cell stages, which suggested that a more "open" chromatin structure might be beneficial for EGA.
Compared with normal fertilized zygotes, in SCNT embryos nuclear, reprogramming has to occur within a short time span, so a more "open" chromatin configuration may be beneficial to SCNT embryos (William et al., 2001; Whitworth et al., 2010; Ogura et al., 2013).
Cells transfected with scrambled SiRNA demonstrated a more open chromatin structure over this 200 bp region.
The activity of MSL is thought to facilitate hyper-transcription by leading to more open chromatin structure.
Increased histone acetylation, such as following HDAC activity pharmacological inhibition, neutralizes the positive charge of lysine residues, allowing a more "open" chromatin structure that facilitates transcription.
